a$)$ because he will agree to your first offer, which is often high.

b$)$ because he will pay full price as quickly as possible, to close the deal.

c$)$ because you can wait until he runs out of time, and then he has to agree to your position.

d$)$ because you can add concessions to your asking price, and he will not notice.
